The act of harvesting a field is often viewed as a purely economic endeavor, a culmination of physical labor and natural growth. Yet, the commandment to separate a portion of the crop elevates this routine agricultural work into an act of divine service. Material wealth is transformed into a profound tool for spiritual closeness, mutual responsibility, and education in reverence for God. The focus of this practice is the Second Tithe, a portion the farmer is required to separate after the initial tithe is given to the Levite. This specific tithe is then taken up to Jerusalem to be consumed in an atmosphere of holiness [רבנו בחיי, אברבנאל].
The placement of this commandment immediately following the prohibition against cooking meat and milk reveals a deeper layer of meaning. The primary approach among commentators links this sequence to the laws of food sanctity. Just as impure meat or a forbidden mixture of meat and dairy is prohibited for consumption everywhere, the holy fruits of the tithe are forbidden to be eaten anywhere outside the chosen place in Jerusalem [אבן עזרא, חזקוני]. Others perceive a conceptual warning in this arrangement. If the Israelites fail to separate their tithes properly, God will send an eastern wind to blast and dry the grain while it is still on the stalk, essentially destroying the crop while it is still in its mother's womb [רש״י, רא״ש, שפתי חכמים]. Maintaining proper boundaries and separating the tithe ensures that God will ripen the fruits in their proper time [קיצור בעל הטורים].
The command to tithe carries a dual promise, impacting both the economic and spiritual realms. Commentators note that the repetition of the instruction to tithe hints at a well-known principle: one should tithe in order to become wealthy. Although there is a general prohibition against testing God, the commandment of charity and tithing serves as the sole exception where a person is permitted to test the divine promise of abundance [כלי יקר, תורה תמימה, צאינה וראינה]. This resulting wealth is not merely a material increase. It is a blessing of peace of mind and contentment, allowing a person to rejoice in their lot rather than endlessly chasing physical desires [חתם סופר]. Conversely, a stingy individual who holds back their tithes will find that the field itself diminishes its yield, ultimately producing only the meager amount the person was originally willing to give [אלשיך, רא״ש]. The dual nature of the command also points to the manner of giving. A person must give twice: once with their hand, and once with their heart, ensuring that the poor are appeased with kind words and a pleasant demeanor [כלי יקר].
The exact scope of the agricultural yield subject to tithing is a matter of discussion. Some maintain that the strict Torah obligation applies exclusively to grain, wine, and oil. In this view, the instruction to tithe the entire crop serves as a warning to the farmer not to tithe merely a portion of the yield while exempting the rest, but to faithfully separate the required amount from the entire harvest [רמב״ן, רש״י]. Other commentators argue that the Torah obligation encompasses all types of seeds and legumes [העמק דבר, מלבי״ם]. To be eligible for tithing, the produce must reach at least a third of its growth and be viable for replanting [הכתב והקבלה]. Furthermore, it must be produce that a person actively gathers into their home and storehouse, excluding ownerless or purchased crops [העמק דבר, תורה תמימה, רלב״ג]. This concept of yield is also expanded by some to include business profits and commercial income, known as the money tithe [תורה תמימה, הדר זקנים], as well as the animal tithe, since livestock is considered a crop that brings a person wealth [הכתב והקבלה, תורה תמימה].
The requirement that the crop must come forth from the field highlights fruits and plants that grow directly from the earth [שד״ל, טור הארוך]. This definition excludes vegetation that is not directly connected to the ground, such as plants grown indoors or in unperforated pots [בכור שור, חזקוני]. On a symbolic level, commentators warn that if a person fails to properly separate their tithes from the field, then the biblical figure most associated with the field, Esau the hunter, will eventually come and seize all their property [צרור המור, נחל קדומים, פענח רזא].
The cyclical requirement to tithe year by year establishes a strict chronological framework. It teaches that one cannot separate a tithe from one year's crop to cover the yield of another year, and certainly cannot mix new and old grain [רש״י, מזרחי, רלב״ג]. It also dictates the cyclical nature of the practice. The Second Tithe is kept for two consecutive years, during which the owners travel to Jerusalem to eat it. However, in the third year of the cycle, the purpose shifts, and it becomes the Poor Tithe, distributed directly to the needy at the city gates [רמב״ן, טור הארוך, אברבנאל].
Ultimately, the annual journey to Jerusalem with the tithed fruits is far more than a financial obligation. It compels the individual to disconnect from the daily burdens of agricultural labor and spend time in the vicinity of the Temple. There, in the presence of the priests, Levites, and the High Court, the farmer absorbs an atmosphere of deep holiness, dedicating time to study Torah and cultivate a reverence for God [רמב״ן, הדר זקנים, רש״ר הירש]. Through the observance of the Sabbath and the faithful giving of tithes, the Israelites purify themselves, refine their inner character, and stand as testaments that they are children of God [פני דוד].
